Detailed explanation-1: -Water is a chemical compound made up of hydrogen and oxygen combined in the ratio 2:1 by volume or 1:8 by mass (2 g of hydrogen combines with 16 g of oxygen).
Detailed explanation-2: -The ratios of Hydrogen to oxygen are 2:1, Hydrogen to water are 1:1, and Oxygen to water is 1:2.
Detailed explanation-3: -The ratio of the volumes of hydrogen and oxygen obtained on electrolysis of water is 2:1. This is because, one molecule of water contains two hydrogen atoms and one oxygen atom in it.
Detailed explanation-4: -Therefore, the ratio of hydrogen and oxygen in water is 2:1.
Detailed explanation-5: -The ratio of hydrogen atoms to oxygen atoms used to make water molecules is always 2:1, no matter how many water molecules are being made. Using formulas to indicate how many atoms of each element we have in a substance, we can relate the number of moles of molecules to the number of moles of atoms.
